Chapter 25, Problem 25.14QAP

Interpretation Introduction

Interpretation:

The titration curve should be developed in spreadsheet format and the limiting current versus the volume of titrant should be plotted.

Concept introduction:

In Amperometric titrations, equivalence point is determined by measuring the electric current produce by the titration reaction under a constant voltage applied. The diffusion current is measured as a function of volume the titrant added. The end point can be obtained by the intersection of the two lines generated for the current before and after the equivalence point.
